摘　　要：随着航空运输业的高速发展,中国航路网络日趋复杂,航路交叉点增多,其对航路容量的影响越来越大,准确计算航路交叉点容量越来越关键。在分析已有航路容量及航路交叉点容量模型的基础上,提出了改进的航路交叉点容量模型和航路容量模型。并在已建立的航路交叉点容量模型的基础上,分析了机型组合、交叉角度和航路长度对航路交叉点容量的影响。取H139与H142两条航路的交叉点进行算例仿真,仿真结果表明:在航路长度和航路交叉角一定的条件下,当机型组合为前机速度大于后机速度时,航路交叉点容量最大;在航路长度相同的条件下,增加航路交叉角就可增加交叉点容量;在交叉角度相同的条件下,增加航路长度也能增加交叉点容量。有穿越高度层情况的航路容量会比没有穿越高度层情况的容量降低9.1%。With the rapid development of aviation transportation, route network becomes more and more complex, the number of route crossing point is increasing, influencing the route capacity. It is more and more privotal to calculate the route crossing point capacity accurately. Based on route crossing point and route capacity models, new models are built. The influences of aircraft combination, crossing angle and longitude on capacity are analyzed. The crossing point of H139 and H142 is taken to simulate these models. Results show that when the velocity of aircraft in front is larger than the aircraft behind, the route crossing point capacity is biggest; when the route＇s longitudes are same, the route crossing point capacity is increased with the increase of crossing angle; when the crossing angles are same, the route crossing point capacity is increased with the increase of longitude ; the route capacity in the situation of flight level changing is decreased by 9.1%.
